So to sum up we don’t how the universe was started, we don’t know what it was made from. We don’t know if there’s other life in the universe. We don’t even know if there’s another planet in our solar system. We don’t know what a quarter of the universe is made from and we don’t know why people need to sleep.

Given their lack of knowledge you’d think a little bit of humility about life and death issues would be in order. Not a bit of it. Peter Saunders gives the low down on the bio-ethics challenges the UK and other societies face.
